The Savannah Airport Commission has been affiliated with Rozin Security for more than seven years. We initially utilized Rozin Security to develop an insider threat mitigation team specific to the commercial airport and airline industry. One of the determining factors specific to Rozin as our choice of developing an Insider Threat Mitigation Team was the Suspicion Indicators Recognition Assessment SIRA and the associated TIPS system.

TIPS technology provides the airport with the ability to track data associated with suspicious activity, thereby connecting the dots in terms of threats to the airport. Rozin Security has assembled one of the best teams of security professionals. Rozin Security provides the airport with a solid methodology in terms of reducing threats as it relates to the insider threat.
